PROCESS OF PRODUCING PERFORATED 0R OPEN-WORK PATTERNS IN FABRICS.

SPECIFICATION forming part of Letters Patent No. 725,823, dated April 21, 1903.

Application filed August 1 5, 1901. Serial No- 72,190. (No specimens.)

To (1 whom it may concern:

Be it known that I, CARLOS CASANOVAS Y AMAT, a subject of the King of Spain, residing and having my post-office address at 1 Oalle Muntados, Barcelona, Spain, have invented a certain new and Improved Process for the Production of Perforated Fabrics, of which the following is a specification.

The present invention relates to an improved process for the production of perforated fabrics by means of substances which chemically destroy the fabric at the parts where they come into contact with the latter, the said substances being applied to the fab ric by mechanical means or by hand.

The accompanying drawing shows a pieceof fabric treated according to this invention.

The process is as follows: I take a uniformly-woven textile material a, made of one kind of textile matter onlyfor example, linen or cambricand print thereon by means of a stamp a suitable chemical substance which will destroy the substance of the fabric at those places b where it comes in contact with it, so as to completely perforate it. This local destruction of the fibers of the fabric is obtained in a very great number of cases by the carbonization of the fibers by treating them with or by applying to them by means of stamps an acid or an acid salt fiber the destruction of both kinds of fiber can be easily effected by stamping the design in acids or acid salts and alkalies or alkaline salts. The stamping can be efiected by hand by means of suitable dies, patterns, or stenoils or mechanically by any suitable system. After the stamping the fabric may be subjected to a high temperature in order to further the carbonization or. destruction of the fiber either by applying hot surfaces or by means of steam or by any other suitable means. The fabricis then printed, if desired, in colors.

I declare that what I claim is An improved process for the production of perforated fabrics, consisting in applying to predetermined places on a uniformly-Woven textile material a chemical substance adapted to destroy the substance of said fabric, thus perforating the same and subsequently printing the fabric, substantially as described.

In witness whereof I have signed this specification in the presence of two witnesses.

CARLOS OASANOVAS Y AMAT.
